VINE : NOTES ON FOSSIL POLYZOA. 
diverse forms were placed together. Some of the species described 
b}" G-oldfuss were ramose, others massive ; and because many of the 
species from the Devonian and Silurian formations, had some apparent 
likeness to Carboniferous fossils found in Yorkshire, Phillips was 
induced to adopt the Genus Calamopora. for the placement of the 
Yorkshire fossils also. 
In the Geolog-y of Yorkshire three species are described, but I 
wish now to direct attention to one of these in particular. 
Calamopora, Goldfuss. 
Geo. of Yorkshire, Ed., 1836. — Stenoj^ora and Chaetetes (Phill). 
" Found mostly in laminar limestone cherts and shales. From the 
Brough Limestone to the Upper Millstone Grit." (op. cit.) 
Calamopora tumida, Phillips. 
Geo. Yorksh., Ed., 1836, PI. I., Figs. 49, 50, 51 only. 
" Irregularly ramified and swollen, formed of concentric layers 
of prismatic cells, contracted to a small opening at the surface. 
Localities — Harrogate, Greenhow-hill. Brough, Kirkby Lonsdale, 
Middleton (Florence Court: Arran, Phill.)" (op. cit.) 
This brief description of C. tumida has caused no end of bother 
to Paleentologists whenever they have attempted to identify species 
in otlier than Yorkshire strata. In my Richmond and Hurst material 
I have several specimens of what I believe to be true C. tumida^ 
Phillips ; and because the specimens differ in many respects from 
others with which they have been associated, I make no apology 
for adding the following' notes to the literature of the species. 
MONTICULIPORA TUMIDA, Phillips.
